This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X800STC, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac SU63-100 Standard Cylinder SU80X800STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X800STC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X800STC is a discontinued double-acting profile-type cylinder with an 80mm bore and 800mm stroke. It features an extruded aluminum barrel and adjustable air cushions at both ends, making it more compact than an ISO 15552 cylinder of the same bore. Delivering 2513 N of push force at 0.5 MPa, it is succeeded by the SAU80X800STC direct replacement. This SAU upgrade retains the exact body, bore, stroke, output force, 3/8" port, and SC-series TC mounting, ensuring a seamless retrofit.
The SAU replacement modernizes the sensor system: this SU model's -S magnet used legacy CS1-B/DS1-B switches, while the SAU utilizes current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU series lacked.

| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Drives large components into housings or applies sustained clamping pressure on bulky assemblies using 2513 N of thrust at 0.5 MPa.
To replace the SU80X800STC, order the SAU80X800STC and verify the 80mm bore, 800mm stroke, 3/8" port (default PT thread), and TC mounting accessory are specified. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors for the SAU. If you need higher force, the neighboring 100mm bore offers 3927 N push at 0.5 MPa; if less is acceptable, the 63mm bore provides 1559 N. For this 800mm stroke, an external guide is strongly recommended to prevent rod bending and side-load damage. A plain cylinder does not hold load on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve if load holding is required. The SAUF variant with a built-in valve is also available if self-switching is desired.
Replacement checklist
Yes, the AirTAC SU80X800STC is discontinued and end-of-life. The direct replacement is the SAU80X800STC. It shares the same 80mm bore, 800mm stroke, 2513 N push force at 0.5 MPa, 3/8" port, and SC-series TC mounting, so it fits the same application directly.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. The -S magnet on this SU works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors. The 3/8" port and M20x1.5 rod thread remain unchanged.
